Overview:

Holley's new GM Muscle Series accessories are the latest expansion to our officially licensed GM product line. These die-cast aluminum valve covers and air cleaner kits were designed to have a no-frills, modern style with prominent raised GM "Chevrolet and Bowtie" logos. Intended as an alternative to the existing GM ZZ6 accessories, Holley's GM Muscle Series dress up accessories can be the perfect addition to your engine bay if you are searching for a subtly custom variation from the OEM options. All GM Muscle Series accessories are available in four custom finishes: natural cast, polished, satin black, and factory orange (all finishes have machined "Chevrolet and Bowtie" logos aside from polished version). The Small Block Chevy center bolt valve covers (designed to fit Vortec/ZZ4/ZZ5/ZZ6) feature a generous internal height for exceptional valve train clearance and include pre-installed internal baffling, polished mounting hardware, and oil fill / PCV grommets (valve cover gaskets not included).

Features:

  • Features clean, modern styling with high definition “Chevrolet and Bowtie” logo
  • Specifically designed for GM ZZ6 engines, but will fit all Small Block Chevy applications with center bolt style cylinder heads (Vortec, ZZ4, ZZ5, ZZ6) – polished mounting hardware included
  • Die-cast aluminum construction ensures high detail and reduces the opportunity for warping of the valve cover flange and oil leaks
  • Emissions compliant valve covers include pre-installed internal oil baffles as well as an oil fill plug and PCV grommet
  • Offered in four unique finishes to fit your style: natural cast aluminum with machined logo (ready for custom paint), polished, satin black with machined logo, and factory orange with machined logo

Great Cargo Net for the Price! 👍
This item is nice and appears to be high quality compared to others that cost way more. So for $15 you cannot ask for better. Now how it holds up over time is another story. My last one was so dry rotted and it stayed stored inside the pocket of my door for several years. Regardless for only$15 if you get 1 year out of it you got your money's worth. Just purchase a new one. As far as seams, stitching and elasticity, it's very good. Carabiners are black coated what looks and feels like aluminum but cannot confirm. The quality as they open and close feel solid. Again time will tell. I would definitely recommend this net. The only negative is the bag it comes in is garbage and cheaply made. It's like dollar general plastic toiletries bag.

Very handy in many situations.
This is a very useful gadget. It is very stretchy, adjustable with extra straps, easy to store in it‘s own bag and a pretty good weight. We used it to transport a mattress, hay bales, a large stack of cardboard boxes and a desk. The hooks are strong but easy to open, it did not tangle for us at all.

Cheap and tough
I got this for a trailer not a truck and it works perfectly for dump runs instead of using a tarp and bungies. Comes in a little bag I'll never use again and had some accessories i don't understand, but if you want a springy net for something that's cheap enough not to care about breaking this is your product
